Got it to work!

I had to port forward (?) in the router, which I did with a LOT of help from my ISP tech support. I also had to email, phone connect, and finally screen share with Source Elements tech support. After trying MANY other things, he finally determined I had to allow "source-connect-loader" through the Windows Defender Firewall.

I gotta say ... getting this to work was VERY VERY non trivial. In my opinion, the Source-Connect (Windows) drivers, documentation, and website all need a LOT of improvement!!! None of this was explained anywhere, and even the SC tech (who was quite good) was not sure to how to make it work and sort of just tried different things out until we got it sorted out. It should not be this convoluted... Phew!
